Measurement method for axisymmetric 3D stress-tensor fields using background-oriented schlieren

open access: yesMechanical Engineering Journal, 2019
Stress fields affect various characteristics of materials. However, measurement methods for three-dimensional stress fields tend to be complicated because stress tensors generally consist of six independent components.

A physics-based machine learning technique rapidly reconstructs the wall-shear stress and pressure fields in coronary arteries

open access: yesFrontiers in Cardiovascular Medicine, 2023
With the global rise of cardiovascular disease including atherosclerosis, there is a high demand for accurate diagnostic tools that can be used during a short consultation. In view of pathology, abnormal blood flow patterns have been demonstrated to be strong predictors of atherosclerotic lesion incidence, location, progression, and rupture. Prediction

Analysis of accuracy of Williams series approximation of stress field in cracked body – influence of area of interest around crack-tip on multi-parameter regression performance [PDF]

open access: yesFracture and Structural Integrity, 2017
A study on the accuracy of an approximation of the stress field in a cracked body is presented. Crack-tip stress tensor is expressed using the linear elastic fracture mechanics (LEFM) theory in this work, more precisely via its multi-parameter ...

A novel reconstruction method for magnetic resonance elastography based on the Helmholtz decomposition

open access: yesMeasurement: Sensors, 2022
We present a novel reconstruction method for magnetic resonance elastography, in which the shear modulus and viscosity of biological tissues are estimated from the externally oscillated displacement field obtained using magnetic resonance imaging.
